Abstract
The utility model relates to a sparkless cutting pick, comprising a pick handle tail part, a clamping ring groove, a pick handle, a pick head, a cladding layer and hard alloy, wherein the pick head is connected with the pick handle which is connected with the pick handle tail part by the clamping ring groove; and the pick head is internally provided with the hard alloy. The sparkless cutting pick is characterized in that the outer layer of the pick head is provided with one cladding layer which is a ceramic alloy powder melting layer with the thickness of more than 1mm. The sparkless cutting pick has the benefits that: by adopting the ceramic alloy powder melting layer, the sparkless cutting pick effectively limits the generation of spark, is beneficial to safety production of coal mine, has strong mechanical property and anti-friction property and long service life, and improves the working efficiency.
Description
Technical field
The utility model relates to coal industry mining machinery consumption part, and specifically a kind of abrasion resistance is strong, do not produce the no-spark pick of spark during with the rock collision friction.
Background technology
At present, pick mechanical property, the friction resistant performance that the coal industry mining machinery is used in the prior art is poor, application life short, a large amount of sparks can occur with the lithosphere friction especially in use, running into has gas and ventilation condition condition of poor, very easily causes security incident.
Summary of the invention
The purpose of this utility model provides the no-spark pick that a kind of abrasion resistance is strong, do not produce spark during with the rock collision friction, the technical scheme that its technical problem that solves the utility model adopts is: structure of the present utility model comprises tooth handle tail, jump ring groove, tooth handle, tooth head, cladding layer, carbide alloy, the tooth head is connected with the tooth handle, the tooth handle is connected with the tooth handle tail by the jump ring groove, be provided with carbide alloy in the tooth head, the skin that it is characterized in that the tooth head is provided with one deck cladding layer, and described cladding layer is that a layer thickness is the ceramal powder crucible zone more than a millimeter.Cladding layer adopts the plasma melting coating technique; with alloy powder or ceramic powders with the tooth head surface rapidly heating and melt, mix, spread, react, solidify, thereby self-excitation cooling back forms hard wear resistant, impact-resistant cladding layer; cladding layer has effectively been protected hard alloy cutter bit; prolonged the application life of pick; ceramal powder crucible zone and rock collision friction do not produce spark substantially simultaneously, have improved the security performance of channel of coal mining working surface.
The beneficial effects of the utility model are, this device adopts ceramal powder crucible zone, effectively suppress spark and produce, and are beneficial to Safety of Coal Mine Production, and mechanical property, strong, the long service life of friction resistant performance have improved operating efficiency.
Description of drawings
Fig. 1 is an embodiment side-looking structural representation of the present utility model;
Fig. 2 partly cuts open structural representation for embodiment side-looking of the present utility model;
Among the figure: tooth handle tail 1, jump ring groove 2, tooth handle 3, tooth head 4, cladding layer 5, carbide alloy 6.
The specific embodiment
With reference to description of drawings the utility model is done following concrete detailed description, as shown in drawings, structure of the present utility model comprises tooth handle tail 1, jump ring groove 2, tooth handle 3, tooth head 4, cladding layer 5, carbide alloy 6, tooth head 4 is connected with tooth handle 3, tooth handle 3 connects by jump ring groove 2 tooth handle tails 1, be provided with carbide alloy 6 in the tooth head 4, it is characterized in that the skin of tooth head 4 is provided with one deck cladding layer 5, described cladding layer 5 is that a layer thickness is the ceramal powder crucible zone more than a millimeter.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
